ICE-PICK.

u SPECIFICATION forming' part of Letters Patent No. 452,555, dated May 19, 1891.`

' Application filed January 3l, 1891. Serial 110.379,80. (No model.)

To all whom t may concern,.-

Beit known that I, FRANK PAUL PFLEGHAR, of New Haven, in the county of New Haven and State of Connecticut, have invented a new and useful Improvement in Ice-Picks, of which the following is a speoication.

My invention relates to an improvement in ice-picks in which a sliding weight is held by the two parts of a shank in position to coutact with an abutment on the shank for the purpose of driving the cutting-edges int'o the ice.

A practical embodiment of my invention is represented in the accompanying drawings, in which'- Figure l represents the pick in side elevation. Fig. 2 represents a transverse section through line :n 0c of Fig. l, and Fig. 3 repreresents a modified form.

On November 25, 1890, Letters Patent of the United States No. 441,333, were granted to A. B. Schoeld for an improvement in icepicks, in which a sliding Weight held by the two parts of a shank was arranged to contact with an abutment on the shank to drive the cutting-edges at the ends of the shank into the ice.

Mypresentinvention oontem plates the forming of the abutment in a pick of the abovedescribed character by means of intertwining the parts of the shank at a point intermediate between the sliding weight and the cutting-edges.

A A represent the two parts of the shank, which are in the present instance represented as the two branches'of a rod or bar bent into U-shaped form, so as to form at one end a loop a for suspending the instrument and at their opposite ends with sharpened edges a', spaced a short distance apart for the purpose of engaging the ice. Aweight Bis provided, as shown in Figs. l and 2, with grooves along its edges to receive the parts A A of the shank, and the same is held in sliding adjustment between the parts of the shank by the twisting of the said parts of the shank together at a point a short distance above the cutting edges or points. The twisted portion is represented at C, and at the points c, where the parts approach each other to form the upper end of the twist, the said parts serve as an abutment, against which the lower end of the weight B impinges as the same is slid downwardly along the shank.

In Fig. 3 the weightB is shownas provided with perfor-ations, through which the parts A A extend, instead of grooves, as shown in Figs. l and 2, and the parts of the shank terminate in points instead of blades.

It is obvious that the two partsA A might be formed separately and united at their upper ends in any well-known or suitable manner.

What I claim isl. An ice-pick comprising a two-'part standard, the ends of the parts being provided with cutting-edges, the two parts bein g intertwined at a point above the cutting-edges, and a sliding weight held between the parts above the intertwined portion, substantially as set forth.

2. The ice-pick having atwo-part standard, the parts being twisted together, forming an abutment, and a sliding weight held between the parts of the standard in position to engage the said abutment, substantially as set forth.
